Title: Fix error for ellipse geometry center position with height

I was seeing weird behavior if the center position of the circle had a height. It looked like it was drawn on the surface, but would disappear if I zoomed in too far. This adds the height of the center position to the `height` parameter, then resets the center position to have a height of 0.
